[PATCH-for-5.1 v3 19/24] hw/riscv/sifive_e: Move some code from realize() to init()

["Philippe Mathieu-Daudé" <f4bug@amsat.org>]

Coccinelle reported:

  $ spatch ... --timeout 60 --sp-file \
    scripts/coccinelle/simplify-init-realize-error_propagate.cocci
  HANDLING: ./hw/riscv/sifive_e.c
  >>> possible moves from riscv_sifive_e_soc_init() to riscv_sifive_e_soc_realize() in ./hw/riscv/sifive_e.c:135

Move the calls using &error_fatal which don't depend on input
updated before realize() to init().

v3: Typo 'depend of' -> 'depend on' (eblake)
